    New lathe thread scioned from the old

    Forgive me, folks, but I didn't want to hijack Jay's thread. On page three, Bart said this:


    "I know a professional turner who's lathe is a chunk of concrete oh about 1000 lbs or more with pillow blocks fastened to the top & I think a 2 HP motor turning I think a 1 1/4" shaft. He turns stuff one wouldn't dare put on a light duty lathe.
    He probably has $200 or a little more in it."


    Hmmmm...

    As you may remember, I had a project to slow down my big lathe, which I had to abandon when I couldn't find a motor with a 4 1/4" 5/8" spindle. But...

    I did do a fair amount of research on VFDs and 3 phase motors. Now, say I left the big lathe as is, and looked at the problem in a wholly different way. Say I wasn't worried about a tailstock? What's actually in a lathe? A motor, two pulleys, a threaded spindle with a bearing, and a face plate. And a way to keep an adjustable toolrest rock steady... Am I missing something?

    Do you see where I'm going here? It's a little crazy, but it's not the craziest idea I've ever had...

    Thanks,

    Bill

    bill, i have a friend who built a lathe for turning outdoors...doing stumps
    he used 2" shaft set in pillow blocks driven by a 125cc dirt bike....the gearing was easy for him to figgure out, just change sprockets....i think he spent around 150 bucks getting the shaft machined?......wrecked dirt bikes usually still run and folks like to get rid of `em for pennies on the dollar after they crash.
    yup it`s doable!

    well, we learn something new every day. For example, today I learned what pillow blocks are. I had no idea... I thought they were some kind of concrete block!

    For those of you who have never seen them, try this:

    But what to attach them to? It would have to be cast iron, I'd bet...

    Thanks,

    Bill

    a few bags of quickcrete and some anchor bolts and you`re pretty stable....
    or an old piece of "i"beam.......even a flattened section of phone pole...
    use your immagination.

    Bill my lathe is homemade, by my grandpa, and it has 2 pillow blocks that are attached to a weld up of angle iron. Works well. I've seen others that used inline blocks attached to hardwood. I will take some close up pics today and post them.

    Bill, there's something like this, but I've seen one much larger that was contructed out of wood using pillow blocks. Unfortunately, I've not been able to locate the link for it.
